Class Visibility (2.17.0)

Visibility restricts service consumer's access to service elements, such as whether an application can call a visibility-restricted method. The restriction is expressed by applying visibility labels on service elements. The visibility labels are elsewhere linked to service consumers.

A service can define multiple visibility labels, but a service consumer should be granted at most one visibility label. Multiple visibility labels for a single service consumer are not supported.

If an element and all its parents have no visibility label, its visibility is unconditionally granted.

Example:

visibility:
  rules:
  - selector: google.calendar.Calendar.EnhancedSearch
    restriction: PREVIEW
  - selector: google.calendar.Calendar.Delegate
    restriction: INTERNAL

Here, all methods are publicly visible except for the restricted methods EnhancedSearch and Delegate.

NOTE: All service configuration rules follow "last one wins" order.
